Application filed September 8, 1914. Serial No. 860,642.

To all whom it may concern.-

Be it known that I, FRANZ CEcKA, a citizen of the German Empire,residing at Chemnitz, in the Kingdom of Saxony, Germany, have inventedcertain new and useful Improvements in Knitted Goods and the Method ofMaking the Same; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference'being had to the accompanying drawing, and to letters orfigures of reference marked thereon, which form a part of thisspecification.

My invention relates to improvements in knitted goods and the method ofmaking the same. The object of the improvements is to provide a methodof making knitted goods in which loops are widened over two or moreneedles, and in which no holes are produced in the fabric by thewidening of the loops.

In making knitted goods the loops are or-. dinarily widened by shiftinga number of loops laterally a distance corresponding to the pitch of theneedles, whereby the needle located at the beginning of the widenedportion becomes disengaged, and a hole is produced in the fabric whichhowever is not objectionable, and can even be removed by hanging on thedisengaged needle the loop of the previous row of loops. Heretofore itwas not possible to widen a number of adjacent loops over two or moreneedles for the reason that at some part a hole was produced whichextends over two loops, so that when continuing the workit wasimpossible to take up the thread for forming further loops. formed.

For certain sorts of goods such loops may be satisfactory. But in smoothfabrics they are objectionable and must be avoided.

However, in some cases the desired form is not obtained by widening oversingle needles and it is desirable to widen two or more loops.

The object of the improvements is to provide a method by means of whichthe loops can be widened over two or more needles without producingladders. "With this object in view my invention consists in interruptingthe series of widened loops in such a way that before the last wideningneedle loops are omitted-in widening.

At such places so called ladders were a For example, if it is desired towiden over two or three needles, a needle must be omitted before thefirst row, and thereafter a further widening needle must be added.

For the purpose of explaining the invention an example of a fabric madeby my improved method has been shown in a diagrammatical way in theaccompanying drawing. I

As appears from the example shown in the drawing the formation ofladders is avoided, because no hole is made which extends over twoneedles, but at two places which are separated by a loop holes of thebreadth of one loop each are formed. 1 1

In the example shown in the drawing widening is to be performed on thepart of the fabric which is at the right ofthe line AB, which partcontains the loops 1, 2, 3, 4, 5, '6, 7. The widening apparatus is madein such a way, that the Widening needle a so acts on the loop 1, that inthe position of the loop 2 there is no widening needle, and that in theposition of the third and following loops before all the further loopsto be widened widening needles 6, c,

d, e, f are located. If after completing the series I the loops arewidened over two needles, loop 1 gets into the position of loop 3, loop3 into the position of loop 5, and each of the following loops isshifted to the right a distance corresponding to the double pitch of theneedles, as appears from row II.

As loop 2 has .not been widened the hole which would otherwise beproduced at the left of widened loop 1 and extend over two needles isreduced to a hole which extends only over one needle, as is shown in rowII at 1, a second hole being produced at the right of the widened loop1, as is shown in row II at 4. As appears from the diagram, whencontinuing the knitting operation at the height of each needle, loopsare formed for the further loops to be produced in row III. In row IVthe widening operation has begun at loop 3, so that the holes are passedover to the right according to the increase in the breadth of thefabric, as is shown in row IV, at 3 aud t The holes which are thusproduced can be closed if desired by known methods, for

example by pulling out a loop from the previous row and hanging the sameon the corresponding needle of. the succeeding row.

An important feature of my invention consists in that the holes whichare produced by thewidening operation are closed or reduced to thedistance of two consecutive needles by the loops which ave not beenwidened. 4 v
